Trained operation personnel of the device must be provably ensured that the treated patient
does not suffer from any aforementioned contraindications and this must be proven by a
signed informed consent.
4. Function Description
The device generates spark discharge and Plasma using DC 5kV with a maximal current of 1
mA which has also an AC part due to an oscillation (instability) of spark discharge. As it has
been already stated, Jett Plasma Lift Medical is a medical device that can be operated only by
a provably trained doctors. The main reason for this is that the energy absorbed by body can
be, in cases of some applications, used for targeted destruction of skin cells.
At the highest levels (6, 7 and 8), this device is used for electro fulguration,
electrodessication and electrocoagulation. The highest intensities (6, 7 and 8) are able to
destroy skin cells. The tip of the device can reach temperatures up to 80°C, when the tip gets
as close to skin as 0,5
–
1 mm. This can be prevented by using a distance glass tube
overreaching the tip by 2 mm.
Electrofulguration is an application of an electric discharge which is enclosed between
the tip of the device and the skin of a patient, when the distance between them is 2 mm. In our
case, electrofulguration affects only a small area of skin, as the generated spark discharge
with the creation of Plasma is not emitted in a wide beam as it is in case of application of AC
electric current. During the application, a doctor can target the treatment area relatively
accurately, for example in case of warts removal and other undesirable skin perturbations.
